Product Description

H.F Welding Machine
Perfect structure designA high frequency Welded Pipe Mill is a machine that is used to produce pipes by welding steel strips together using high frequency electrical current. The process involves feeding steel strips through a series of rollers, which shape the strips into a cylindrical shape. The edges of the strips are then heated using high frequency electrical current, which melts the metal and fuses the edges together. The welded pipe is then cooled and cut to the desired length.Solid State H.F Welding Machine
Perfect structure design
l Independent design of switchgear rectifying cabinet and inverter output cabinet, connected by soft cable, which is convenient for layout at user’s site.
l The rectifier adopts 3-phase 6-pulse thyristor rectifying. For large power welder, 12-pulse thyristor rectifying can be selected to eliminate grid side fifth and seventh harmonic, and grid side harmonic current is the lowest.
l Power combination of the inverter bridge is accomplished by the way of power unit superposition. Each MOSFET power unit is designed to be 50kW/100kW/150kW and slideway drawer structure, which is convenient for installation and repair.
l High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.
l Closed cabinet design, meeting rigor environmental requirements on site.
* The user needs to prepare three winding power transformer.
